The caterpillar of the Wavy-lined Emerald Moth (Synchlora aerata) sticks bits of plant material to itself.
I’ve seen this before, but only on instars half this size. Nice to be able to get some feet in these shots.
FYI: some green lacewings stick clumps of lichen to their backs. Try as I might, though, I couldn’t get any photographs of two recent sightings.
Backyard and Beyond 
This looks like a child’s drawing of a scary monster. No matter what the human mind concieives nature has already done it. Usually more scary and yet still beautiful.
